Have You Ever Seen A Smack of Jellyfish? An Alphabet Book by Sarah Asper-Smith

What do you call a group of kangaroos?  A troop!  What do you call a group of frogs?  A knot
OK, I admit it.  I did not know the answers to these questions either!  This simple ABC book is fascinating.  Each animal's group is identified.  Each illustration is illustrated with appropriate background and the animals are black shadow.
